PBA boss Patrick Lynch (speaking) said the families of the deceased cops deserve the money in Herman Bell's commissary account.

Cop-killer Herman Bell’s attorney shot back at the Patrolmen’s Benevolent Association Tuesday, calling the union “petty” for trying to seize more than $10,000 from the prisoner’s commissary account.

“The PBA’s action is petty and vindictive, and appears calculated to do nothing more than cause suffering,” said Bell’s attorney, Robert Boyle. “Justice is not served by vengeance.”

The union announced Sunday it has taken legal action under the Son of Sam law to acquire more than $10,000 from the inmate’s account. If procured, the funds would be given to the families of fallen NYPD Officers Joseph Piagentini and Waverly Jones, who were killed May 21, 1971 at the at the Colonial Park Houses — now the Rangel Houses — on W. 159th St. in Harlem. Bell, 67, is serving a life sentence for the murders.

Boyle said the suit will do little to make things right.

Herman Bellis serving life in prison for murdering two cops in 1971.

“The last thing Herman Bell wants to do is cause further grief to the family of the victims. He realizes that even after 42 years, the pain of the family doesn’t go away.

“But he and his family have already paid their debts,” Boyle added, referring to the decades his client has already served behind bars.

PBA President Pat Lynch said Bell can never repay the families, and are more than deserving of the cash.

“He has denied two families the priceless warmth and love of a husband and father,” Lynch said. “Absent a viable death penalty, justice will be served by Herman Bell remaining in prison for the rest of his life.”

When asked if Bell wanted to give the funds to the victims’ families, Boyle said, “probably not.”

The attorney said he does not know how much money Bell has in the account, or how that money was acquired.

Prisoners can generate funds for work performed in prison, through outside contributions, or, in some cases, from civil suits filed by the inmate.

Families are notified by The New York State Crime Victim Compensation Board when a prisoner account reaches more than $10,000.
